Snout blunt, rounded in dorsal view, much shorter than eye diameter. Eye large to of SL. Interorbital narrow, about half eye diameter. Mouth short reaching to a point below middle to end of pupil. Upper jaw length to SL in females and SL in male. Anterior nostril tubular with a large posterior branched tentacle, composed of 3 to 6 elongate lobes; anterior nostril positioned about half way between snout tip and posterior nostril. Posterior nostril with a raised rim, positioned above anterior margin of eye. Orbital tentacle (Fig. 7) flattened with 5 to 10 slender lobes extending from base; length to of Fig. 5. Female holotype of Heteroclinus macrophthalmus, 64 mm SL, based on preserved colouration. First dorsal fin higher than second; first and second dorsal spines about equal in length, third spine slightly shorter. Second spine SL in 39 mm male and and SL in large females. First dorsal origin over end of posterior margin of preoperculum, last spine above a point behind middle of operculum. Membrane of first dorsal fin separate from second dorsal or connected to second dorsal at very base. Tips of first 3 dorsal spines with 3-6 elongate free flaps. First spine in second dorsal fin without flaps. Tip of second spine in second dorsal fin with 1 or 2 free flaps. Tips of remaining dorsal spines with an elongate free flap. Second dorsal origin above a point behind pelvic insertion. Anteriorly spines in second dorsal fin short, becoming progressively longer posteriorly, last spine to of SL; first ray longer than last dorsal spine. Dorsal rays evenly spaced. Last dorsal ray connected by membrane to caudal base. Anal origin below 11th and 12th spine in second dorsal fin. Posterior rays of anal becoming progressively longer; last ray short
